I would be almost certain that your bug stems from changes to GCC, 
not changes to BPL. Generally speaking GCC bugs fix themselves over 
time, so you can revert temporarily to an older GCC. Bugs in GCC are 
common enough that if my code fails, I first think it's GCC's fault 
:)

Try an older GCC. Also, try Clang. Clang seems to generate better 
debug info for templates anyway.
